Summary: | The present invention relates to a polymer, which contains a structural unit having a carboxyl group represented by the following formula (1) at a side chain of the structural unit, and which comprises an acid group represented by the following formula (4) having an acid dissociation constant (pKa) of from 0 to 11 at a side chain of the polymer:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ P-X 3 -(A 2 -H) m €ƒ€ƒ€ƒ€ƒ€ƒ(4)
wherein in formula (1), R 1 represents a hydrogen atom or a methyl group; R 2 represents an (n+1)-valent organic linking group containing an ester group represented by -O(C=O)-; A represents an oxygen atom or NR 3 -; R 3 represents a hydrogen atom, or an monovalent hydrocarbon group having from 1 to 10 carbon atoms; and n indicates an integer of from 1 to 5;
and in formula (4), X 3 represents a single bond that directly links to a main chain of the polymer, or a linking group selected from a group consisting of a carboxylic acid ester group (-COO-), an amido group (-CONH-), a hydrocarbon group and an ether group (-O-or -S-); A 2 -H represents a partial structure that functions as an acid group having an acid dissociation constant (pKa) of from 0 to 11; and m indicates an integer of from 1 to 5. |
